Boston Mineral Club
Welcome to the Boston Mineral Club website! If you have suggestions, questions or comments about the site, please use the Contact page.
You do not need a college degree in earth sciences to join the club! We are open to all. We welcome and encourage new members to join the club. Membership
The Boston Mineral Club (BMC) was founded in 1936 to "promote the study and collecting of rocks and minerals, to encourage friendly cooperation among mineralogists and collectors, [and] to promote the study of mineralogy and related arts and sciences coming within the purview of earth sciences..."
In the pursuit of these goals, the BMC offers educational programs at club meetings, mineral collecting field trips, a newsletter, and access to our mineralogical reference library.
The Boston Mineral Club is a member of the American Federation of Mineral Societies and the Eastern Federation of Mineral and Lapidary Societies. The BMC also is recognized by the IRS as a 501(c)(3) educational organization.
The Boston Mineral Club is proud of its long tradition of conducting field trips to collecting localities throughout the New England area. Information about trips planned for the current year is published in our newsletters which can be found in the members only area of the website.
The club also organizes occasional trips to localities outside of New England. Previous destinations have included Nova Scotia, Kentucky, Georgia and Arizona. You can view photos of our 2009 trip to Nova Scotia here: Nova Scotia 2009.
Information about the regular monthly meetings of the club can be found on the meetings page.
The May meeting of the Boston Mineral Club will feature a presentation by Ted Johnson on the mineralogy of the Tilly Foster Iron Mine in Brewster, New York. This mine exploited a large magnetite deposit that was discovered in 1810. The mine is a near Brewster but is actually in the defunct hamlet of Tilly Foster, which is now partly submerged by the Middle Branch Reservoir. The mine was 600 feet deep in 1879. Mining ceased in 1897, after 13 miners were killed in a rockslide. The mine is well-known for its excellent brucite, chondrodite, clinochlore, titanite, and magnetite crystals and antigorite or lizardite (and other species) pseudomorphs after a wide variety of minerals. Additional information including specimen photographs and its extensive species list can be found on Mindat at http://www.mindat.org/loc-4004.html.
Ted Johnson is a knowledgeable mineral collector and dealer who has traveled extensively to experience, first hand, some of the classic mineral localities throughout the world. He has given a number of presentations at BMC meetings over the years. Although he is now retired from the nuclear power industry, he remains the proprietor of Yankee Minerals and is a regular participant in a number of New England mineral shows.
The presentation will begin with an abbreviated history of the Tilly Foster Iron mine and also will discuss the primary researchers and collectors that have contributed to the knowledge mineralogy of the mine, including the significant contributions made by Ron Januzzi. The remainder of the presentation will focus on the mineralogy of the Tilly Foster Iron mine, highlighting the collection of Ron Januzzi. Many rarely seen micro’s will be shown.
The discussion will cover many of the species and varieties found at the mine, including silicates- (approx. 50), carbonates- (approx. 10), sulphides- (approx. 10), 3 elements, 1 halide, oxides- (approx 11), sulfates- (approx 12) and 3 Phosphates. Ted will also discuss the list of Tilly Foster pseudomorphs, for which the mine is famous. Finally, the presentation will conclude with a dedication to Ron Januzzi for his life long study of Tilly Foster mineralogy.
To complement the presentation all BMC members are invited to bring in and display any interesting mineral specimens that they have in their collections from any NY locality. The BMC display case will be available. Prior to our meeting the mineral hall of the Harvard Geological and Mineral Museum will be available to us from 7 to 8 PM. We will gather in Haller Hall for refreshments and socializing beginning around 7:30 PM. At 8 PM we will begin our short business meeting followed by the presentation. The evening will conclude with our traditional mineral raffle. Please plan to come and invite a friend to come with you. Our meetings are open to everyone!
